Title: Speech recognition
Inventor: SIMONS ALISON DIANE
IPC: G06F19/00
Filed: 1996-03-07
Abstract: A recogniser is provided with a priori probability values (e.g. from some previous recognition) indicating how likely the vari-ous words of the recogniser's vocabulary are to occur in the particular context, and recog-nition "scores" are weighted by these values before a result (or results) is chosen. The recognises also employs "pruning" whereby low-scoring partial results are discarded, so as to speed the recognition process. To avoid premature pruning of the more likely words, probability values are applied before the pruning decisions are made. A method of applying these probability values is de-scribed.

Abstract: A machine for producing a wooden element made up of parallel rows of bars comprises a tape-applying device (15, 17, 18, 19) intended for such application of a strip of adhesive tape (16) on pairs of adjacent rows in parallel therewith that the strip of adhesive tape (16) joins the rows together, as well as a cutting device (23) intended to cut the material web made up of the thus-joined bar rows into predetermined lengths. The cutting device (23) has a reciprocatingly movable carriage (24) provided with a rear cutting unit (32) and a front stop element (37), the distance between the latter being adjustable according to the aimed-at cutting length. When fed forwards, the material web impinges upon the stop element (37), thereby to displace the carriage (24) from an initial position to a turning position. The cutting unit (32) performs a cutting operation during this displacement of the carriage (24). Before the carriage (24) reaches its turning position, the stop element (37) is removed in order to release the cut-off length of material web, thus enabling it to be discharged from the machine. A discharge conveyor (26) discharges the cut-off length of material web at a speed exceeding that at which the material web is fed in the remainder of the machine. A return element (41) returns the carriage (24) to its initial position.

Title: Prosthetic graft and method for aneurysm repair
Inventor: ORTH GEOFFREY A
IPC: A61F2/07
Filed: 1996-06-05
Abstract: This invention provides a method and graft system for aneurysm repair comprising a prosthetic graft with means to draw a distal extremity of the graft over a portion of an expandable anchoring member. Prior to deployment, the graft and the anchoring member do not overlap to reduce the outer diameter of the delivery system. Preferably, the drawing means comprises pull strands connected to the distal extremity of the graft so that the distal extremity of the graft may be pulled over a proximal portion of the anchoring member. Subsequent expansion of the anchoring member seals the overlapped graft against the vessel wall to minimize blood flow-by and secures the graft in the vessel. Securing means may be advanced up each pull strand to abut the anchoring member and further secure the graft to the anchoring member. The graft may also comprise means to guide a second expandable anchoring member to the proximal end of the graft. Preferably, the guiding means comprise guide strands connected to a proximal extremity of the graft. The anchoring member can then be advanced up the guide strands until the graft overlaps the second anchoring member.  Expansion of the second anchoring member secures the proximal end of the graft.

Patent CA-2237339-A1 (CA)
Title: Bearing for high speed coil winding
Inventor: TUCKER JAMES T
IPC: H01F5/00
Filed: 1997-09-10
Abstract: A bearing for maintaining a bobbin in relative position about a transformer core leg during the winding of a coil on the bobbin. The bearing is movable along the core leg such that a bearing surface of the bearing is positioned adjacent to but not touching each of two outwardly facing surfaces of two spaced apart flanges of the bobbin. The bearing surface is highly polished to reduce friction. The bearing surface preferably includes a circumferential ridge centered about the axis of the transformer core leg on which the bobbin is positioned. The outwardly facing surfaces of the two flanges each include a concentric groove shaped to complement the circumferential ridges of the bearing surfaces. When the bearing is in position the circumferential ridges are partially received within the concentric groove such that a small gap is maintained between the bearing surfaces and the outwardly facing surfaces. The bearing surface can also include ports for exhausting low pressure air into the space between the bearing surface and the outside surface of the bobbin flange. The low pressure air cools the bearing surface and acts as a cushion between the bearing and the bobbin flanges.

Title: Actionnement echelonne de dalles electromagnetiques pour la regulation de la couche limite
Inventor: NOSENCHUCK DANIEL M
IPC: F15D1/12
Filed: 1996-11-19
Abstract: Un dispositif qui permet de réguler une couche limite dans un flux de fluide conducteur se déplaçant par rapport à une surface dans le sens de l'écoulement libre comprend une pluralité de dalles disposées dans des zones de régulation, sélectivement actionnées (406, 506), distribuées sur toute la surface (104) en rangées dirigées dans le sens de l'écoulement et dans un sens transversal par rapport à ce dernier. Chaque dalle (406, 506) est fixée par un dispositif générant un champ magnétique (101, 102) qui permet de générer dans le fluide un champ magnétique dont les lignes de flux ont une orientation prédéterminée par rapport au sens de l'écoulement libre. Il en résulte une distribution tourbillonnaire qui actionne les dalles (406, 506) et crée ainsi des zones de régulation. Celles-ci introduisent dans le flux une distribution tourbillonnaire, au-dessus de chaque zone de régulation, ce qui permet, au-dessus de la rangée, de réduire le tourbillonnement contre la paroi dans le sens transversal par rapport à l'écoulement libre et d'empêcher la création de concentrations de tourbillons à l'intérieur de la couche limite dans le sens de l'écoulement libre.
Patent CA-2239354-A1 (CA)
Inventor: HAIGH NEIL RICHARD
IPC: H04B10/071
Filed: 1996-12-19
Abstract: An optical line system comprises: (i) an optical fibre that includes a plurality of reflectors, for example Bragg gratings, located at different positions along the optical fibre; and (ii) a monitoring arrangement located in the region of one end of the optical fibre for monitoring the system by an optical reflectometry method in which light is reflected by the reflectors. The system is characterised in that at least two of the reflectors have reflectivities that differ from one another, the reflector that is more distant from the monitoring arrangement having a higher reflectivity than the Bragg grating that is nearer to the monitoring arrangement. Preferably the reflectivities of the reflectors increases as the distance from the monitoring arrangement increase, the reflectivities preferably having the relationship (I) Rn-1=(2T2Rn+1)-(1+4T2Rn)1/2/2T2Rn where: Rn is the reflectivity of the n th reflector from the monitoring arrangement Rn-1 is the reflectivity of the (n-1)th reflector from the monitoring arrangement, and T is the transmission coefficient of any branch that may be present between the (n-1)th and the n th reflector (and is unity if no such branch exists). Such a system has the advantage that the signal-to-noise ratio of the most distant reflectors is increased by the greatest extent so that differences in the signal-to-noise ratio of different reflectors is reduced.
